It is simply a bit wet in the Summers (no fuel drops at all)... BUT it leaks in Winters (this has to do with the cold weather, I`m sure... my Power Steering fluid does the same actually)
But, I know, the injection pump should NOT leak and should not even get wet, AT ALL.

It leaks (I think) at the top seal on the drivers side of the pump (left side of car). Maybe the seal can be done in-car.
IF pump comes off then I`d love to send it up to Maine! but my spare pumps are not turbo-diesel pumps (damn!). I don't think a td motor would run well with my d24 nonturbo pump (if that`s a good idea at all. idk)

Is there a `treatment fluid` that may help inj.pump seals swollen up enough to somewhat correct the leak??
I know that the real biodiesel (b99) is a great help. I just can`t get it anywhere nowdays. Is there something (fluid, additive, oil, etc) that may work as such?

Other.
I`m planning on a double can of LubroMolly diesel purge btw (have it on the shelf since last year when I decided to care for my injectors but I actually ran the car on a liter of ATF and it helped clear out some goo. Maybe.. I'm not sure. Maybe as much as an italian tune-up can do. LOL
This time I would remove the return fuel line and do the purge the right way (not just adding atf into fuel filter or run car from a jar).

I'm sure a diesel fuel filter is a very nice idea to remain in the system for the time of the purge. I think I want to do it with a filter still active.
My fresh Bosch filter has only a few 100 miles on it. Shall I get a new one and do it with that? Dirt particles can get released by lubromolly, coming from my slightly used filter and they perhaps *could* get into injectors or pump. Filter has low miles. IDK if that is a real threat though.

If it is indeed the top cover seal, you could try incrementally tightening up the cover screws first. Otherwise, the cover gasket can be replaced in-car. Make sure you use the correct gasket, not the thicker one with the nubs. Tricky part with this method is keeping the throttle lever linkage connected to the governor spring cage while reinstalling the cover.

I have one that was leaking out the mainshaft seal when running good quality B100. It stopped leaking after switching to Petro Diesel. Sorry, I didn't know B99 was able to seal leaks. I DO know that B2 has been proven to help lubricate the IP and injectors, adding in the lubrication properties that were removed when LSD (Low Sulfur Diesel) was mandated.

What "goo" were you able to observe removed? Some of the IPs I have disassembled had a brownish varnish coating the internals, and some sediment at the bottom. Not sure a 5-minute LubroMoly purge would be able to remove this. One, that was run on WVO did have some chicken-skin flakes of polymerized WVO inside-- NO solvent has yet been found to remove this. Sometimes an IP stored improperly for several years will have some goo inside. This would require disassembly and scrubbing with solvent to remove it.

Not following you here. Dirt particles released from where? To me, the biggest threat with this process is knocking some foreign material into your feedline which then gets sucked directly into the IP.

What problem are you hoping to solve by mainlining LubroMoly? Seems like we are easy to get suckered into paying $$$ for a feelgood "treat" or vitamin to our car, just like some are easy to get suckered into snakeoil miracle remedies for arthritis, baldness, backpain, etc.
